What Are Tennessee Onions?
Tennessee Onions is a classic Southern recipe made with thick slices of sweet onions baked in a creamy, cheesy sauce. Often associated with potlucks and family gatherings, this dish is known for its rich flavor, tender texture, and versatility. It’s incredibly easy to make, requiring just a handful of ingredients and minimal prep time.
Ingredients You’ll Need
To make a 9x13-inch casserole of Tennessee Onions, gather the following:
3–4 large sweet onions (like Vidalia or Walla Walla)
1 stick (½ cup) unsalted butter, melted
2 cups shredded cheese (a blend of mozzarella and sharp cheddar works best)
1 cup heavy cream
½ teaspoon garlic powder
½ teaspoon onion powder
½ teaspoon paprika (optional, for a smoky flavor)
Salt and pepper to taste
½ cup crushed Ritz crackers or panko breadcrumbs (for topping)
Fresh parsley or chives (for garnish, optional)
Step-by-Step Instructions
Step 1: Prep the Onions
Peel the onions and slice them into thick rings, about ½-inch wide. Keep the rings intact for a beautiful presentation.
Separate the rings gently, discarding the small center pieces or reserving them for another use.
Pro Tip: Sweet onions are essential for this recipe, as their natural sugars balance the richness of the cheese and cream.
Step 2: Preheat Your Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with butter or nonstick cooking spray to prevent sticking.
Step 3: Layer the Onions
Arrange the onion rings in a single layer in the prepared baking dish. Slightly overlap them if needed to ensure they fit.
Pour the melted butter evenly over the onions, coating them thoroughly.
Why This Step Matters: The butter adds richness and helps the onio
ns caramelize while baking.
Step 4: Add the Cheese
Sprinkle the shredded cheese evenly over the onion rings, ensuring full coverage.
You can mix mozzarella and cheddar for a balance of creaminess and sharpness. Feel free to experiment with other cheeses like Monterey Jack or Gruyere.
Step 5: Prepare the Cream Mixture
In a small bowl, whisk together the heavy cream, garlic powder, onion powder, paprika, salt, and pepper.
Pour the mixture evenly over the onions and cheese. This will create a creamy, cheesy sauce as the dish bakes.
Step 6: Add the Crunchy Topping
Crush the Ritz crackers or use panko breadcrumbs and sprinkle them evenly over the top.
This adds a crunchy contrast to the soft, creamy onions beneath.
Step 7: Bake the Casserole
Cover the dish with aluminum foil and bake in the preheated oven for 25 minutes.
Remove the foil and bake for an additional 20–25 minutes, or until the cheese is bubbly and the top is golden brown.
Pro Tip: Broil the dish for 1–2 minutes at the end to achieve an extra-crispy topping. Watch closely to prevent burning.
Step 8: Garnish and Serve
Let the casserole cool for 5–10 minutes to set before serving.
Garnish with chopped parsley or chives for a fresh, vibrant touch.
Serving Suggestions
Tennessee Onions pair wonderfully with grilled meats, roasted chicken, or holiday favorites like ham and turkey. Serve it alongside mashed potatoes, green beans, or a fresh salad for a complete meal. It’s also delicious as a standalone dish with warm crusty bread to soak up the creamy sauce.
Tips for Perfect Tennessee Onions
Choose Sweet Onions: Vidalia onions are the gold standard for this recipe due to their natural sweetness, but any sweet variety will work.
Make Ahead: You can assemble the casserole a day in advance, cover it tightly, and refrigerate it. Bake it fresh when you’re ready to serve.
Customize the Toppings: Swap the crackers for breadcrumbs, crushed pretzels, or even fried onions for added texture and flavor.
Experiment with Add-Ins: Add crumbled bacon, diced jalapeños, or a sprinkle of Parmesan for a personalized twist.
Storing and Reheating
Refrigeration: Store leftovers in an airtight container in the fridge for up to 3 days.
Reheating: Warm in a 350°F oven for 10–15 minutes or microwave individual portions for 1–2 minutes.
Freezing: While best fresh, you can freeze the casserole before baking. Wrap it tightly in foil and freeze for up to 2 months. Thaw overnight in the fridge before baking.
Tennessee Onions is the kind of dish that brings comfort and joy to the table. With its creamy, cheesy layers and tender onions, it’s a recipe that’s sure to impress at family gatherings or casual dinners alike.
